lengthwise of the drum thereby varying the VOlll-r metric capacity ofthe latter. As will be clear the screws 27 hold the walls 26 fixedly inadjusted position. 1

A given volume of coal of one grade or kind will weigh less than coal ofanother grade or kind' and therefore it is an advantage to so constructthe drum that its volumetric capacity can be variedas may be required bythe kind orgrade of coal that is being packaged. r

- The end' spiders 22 may be disks of metal, as

shown, formed with holes or ports 28-through which-is discharged bygrav'ityany dust-or particlesof coal which may find its way into thespaces between the partition walls 26 and the spiders'22. 3

The axle trunnion 23 has fixed thereon a member- 29 provided-with tworadially disposed abutmerit arms 30 and 31 which are at opposite sidesofthe axis of said trunnion axle. Alongside of member 29, and looselymounted on the axle trunnion 23, is a sprocket-wheel 32 around whichpasses a flexibleendless power transmitting chain 33 which is also-inengagement with a sprocket wh'eel- 34-fast-on a transverse shaft 35journaled in bearings on the frame 10 of the machine.

n Shaft 35 also has faLstenedthereon a pulley 36 connected by a be1t3'7witha pulley38 fast on the armature shaftof an electric motor M'that isfixed in position on frame 10.

-The' motor M is adapted to be connectedby circuit wires (not shown)with-a source of current a and a manually operated make and break switch(notshown) may be mounted on frame 10 and connected in circuit withmotor M,-if desired;

The endless chain 33 is provided withalaterally projecting arm 39 whichis in the same vertical plane with the two abutment arms 30 andJ3l. Whenthe motor -M is operating the chain. 33 is driven continuously in thedirectionindicated;by the arrow 'in Fig. 1 and it will beclear thataftertheportion of said chainwhich carries the arm 39 is brought intoengagement with sprocket 32, and

' assaid armtravels aroundthe axis thereof, it will pick upand mcvethearm 30 with it .to the extent of one-half of a revolution at the endof which thearm39 disengages the arm and moves away from sprocket 32 ona tangential path.

As pointed out above the radialabutinent arms 30 and ,31 are angularlydisposed 180 apart so that when one of said arms is picked up by arm 39and swung around the axis of trunnion 23 to vI the extent of one-half ofa revolution, the other abutment. arm takes its place in the path of arm39 'and will bejsimilarly'foperated thereby the next time arm 3 9 makesthe'circuit" of its orbit;

Thus when the machineis inluse the drum 16 I is intermittently turnedstep-by-step in a contraclockwisedirection (Fig. l) each step movementbeing tothe extent of one-half revolution. The abutment arms 30 and 31are set on axle trunnion 23 sothat during alternate'periods of restthereof the drum passage or port 25 is in register with the outlet 15 ofthe hopper and during the other periods of rest the passage 25 is at thebottom of the drum.

Thus each time the passage or port 25 is brought into register with thehopper outlet the drum is filled with coal or other material from thehopper and each time the drum is turned to bring. its passage or port 25at the bottom thereof its contents is discharged into the deliveryfunnel 21.

The funnel 21 is made at its bottom with an outlet 40 which extendsthrough a spout 41 that is provided upon the exterior of the funnel Iand on which the mouth portion of a bag is adapted to befittedtelescopically so that each load of material that is discharged into thedelivery funnel by the measuring drum is delivered into a separate bagapplied to the spout 41 in this manner.

The. chain drive for the abutmentarms '30 and 31 not only effectsintermittent step-by-step movement of themeasuring drum but its lengthaifords sufficient time between delivery operations of the drum-for theoperator 1 toremove a filled bag from spout 41 and substitute an emptybag. 1

It=willbe -clear-that-' clogging at the hopper outlet 15 which wouldotherwisetend tostop the movement of the drum is prevented by: theyielding closure member .18.. Sticks of wood and other objects are oftenfound inc'oal and except for the yielding closure member 18 would tendto'clog and stop the operation of the machine.

During each period of rest of themeasuring drum it is held againstaccidental rotative dis.-. placement by means of a spring presseddetent, herein shown-as a ball, which at such tiinesoc-v cupies oneorthe other of two sockets 46 ;provided upon the periphery. of a wheel 4J7fast on axle trunnion 24.- The detent.45. and. its spring.

48 are mounted. WithinJa chamber 49. formed in a bracket 50 that issecured to theframe 10;

3. In a machine of of the character described, the combination of arotatably supported measuring drum provided with a supporting axle thatis rigidly connected with one end thereof; a pair of radially disposedabutment arms fast on said axle, one at each side, thereof; a wheelloosely mounted on said axle alongside of said abutment arms; a secondwheel; a motor for'continuously rotating said second wheel in onedirection, and an endless flexible power transmitting member supportedbysaid two wheels and driven by said second wheel, said member having anarm for engaging the abutment arms of said pair individually inalternation as it repeatedly traverses its orbit thereby tointermittently turn said drum on its axis step-by-step in one direction.

4. A bag loading machine comprising a frame; a hopper fixed to saidframe and having an outlet at its bottom; a hollow measuring drumrotatably supported by said frame beneath and in close proximity to saidoutlet so as to turn on a horizontal axis and so as to serve at times asa closure for said outlet, the side wallof said drum being made with apassage adapted to register with said outlet so that said drum is filledby gravity with material from said hopper; a delivery funnel fixed tosaid frame beneath said drum into which the contents of the latter isdelivered by gravity when said passage is below the axis of the drum,said delivery funnel having an outlet at its bottom through which itscontents is discharged by gravity and a spout surrounding said outletfor holding the mouth of a bag in position to receive the material thatis discharged through said outlet; an axle journaled on said frame andconnected with said drum; a pair of radially disposed abutment arms faston said axle, one at each side thereof; a wheel loosely mounted on saidaxle alongside, of said abutment arms; a second wheel rotatablysupported by said frame; a motor mounted on said frame for continuouslyrotating said second wheel in one direction, and an endless flexiblepower transmitting member supported by said two wheels and driven .bysaid second wheel; said member having an arm for engaging the abutmentarms of said pair individually in alternation as it repeatedly traversesits orbit thereby to intermittently turn said drum on its axisstep-by-step in one direction. i e
